A couple who has lost 178 pounds

We have followed strict Dr. Berg's keto since April 20, 2019. Ted (58) lost 75 and I (62) lost 78 lbs in 9 months. As of Feb. 2021, Ted has lost 100lbs. I continue to work on my last 60lbs. We both feel great and live a complete Dr. Berg lifestyle. Ted was diagnosed with bladder cancer in 2016 and has been clean. Unfortunately, 4 weeks ago they found a rectal tumor, and he is about to undergo Chemo 6/28/21. I wanted to share our story as we continue our Dr. Berg story. I need info about nutrition while on Chemo. He is very thin right now. Dianna.
